Do any of the members have experience, good or bad, running the newer (black box with picture of brass cased 45) S&B ammo in their '28's or M1/M1A1? I have the opportunity to pick up several cases of this ammo at a fantastic price but I've never run the newer ammo. I was trying to find the red,white and green boxed ammo but have had no success. Is there a difference between the two? Thank you for any and all opinions.
